Description

Technical Field

[0001] The utility model relates to the technical field of battery installation, in particular to an adjustable stop frame profiling block. Background Art

[0002] The assembly line is an important production process of lithium-ion batteries, and its process flow includes wrapping. Film wrapping is an important part of the lithium battery production process. By covering a layer of mylar film on the outer layer of the battery cell, it is ensured that during the process of installing the battery cell into the battery case, the relative movement between the battery cell and the case will not cause damage to the battery cell body.

[0003] The film wrapped on the battery cell is a mylar film. The mylar film is square and is wound around the battery cell to form a square tubular protective film, which is temporarily fixed by tape. After the mylar film is wrapped on the battery cell, the two ends of the tubular protective film formed by the mylar film also need to be fixed on the battery cell. Since the battery cell itself cannot be fixed, stop frames are sleeved on both ends of the battery cell, and the film edges at both ends of the tubular protective film are thermally connected to the stop frames; due to the technical requirements for wrapping the mylar film, the mylar needs to be wrapped flat, close to the battery cell, without turning over or wrinkling. Therefore, whether the position of the stop frame is accurate is the key point.

[0004] When assembling the stop frame, a profiling block is required to position it to ensure the spatial position of the stop frame body and the relative positions of each structure and the battery cell, so as to ensure the wrapping effect and the melting point position when wrapping the mylar film. In the assembly of the battery, the battery will have different sizes, and the stop frame is manufactured corresponding to the battery cell, so the stop frame also has different sizes. Usually, they are all rectangular. When installing the stop frame, a specific profiling block is required for installation, and it cannot be used for installing multiple stop frames, which causes inconvenience. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an adjustable stop frame profiling block to solve the problem that the profiling block cannot be used for installing stop frames of different sizes.

[0006] Based on the technical problems existing in the background art, the utility model proposes an adjustable stop frame profiling block, which includes two base blocks connected by an adjustment mechanism to form a base plate. At both ends of the base plate, limit blocks are fixed by bolts on the same surface, and clamping blocks are fixed by bolts on the surface of the limit blocks away from the base plate. The adjustment mechanism can adjust the interval between the two base blocks, and by changing the interval between the two base blocks, the distance between the two clamping blocks is adjusted to adapt to the installation of different stop frames.

[0007] Preferably, the limiting block is a cuboid and is vertically installed on the substrate. The limiting block is installed on the side of the base block, and there is a gap between the two limiting blocks. When installing the stop frame, the tab of the battery cell can pass through the stop frame and be located within the gap between the two limiting blocks.

[0008] Preferably, two plate bodies can also be installed on the upper and lower surfaces of the base block through bolts. The two plate bodies and the limiting block are arranged in a U shape on the base block. The two base blocks can be adjusted to be close to each other through an adjusting mechanism to form a mouth-shaped groove. The two plate bodies can block in the longitudinal position of the base block, so that the tab of the battery cell is located between the two plate bodies, avoiding damage to the tab of the battery cell.

[0009] Preferably, a card slot is formed on the surface of the limiting block away from the base block, and the card block is embedded in the card slot and fixed by bolts. The shape of the card slot is the same as the cross-sectional shape of the card block, which can allow the card block to be embedded in the card slot for installation and prevent the card block from rotating.

[0010] Preferably, a screw groove for installing bolts is formed on the surface of the card block away from the limiting block, and the nut of the bolt does not protrude from the screw groove. When the stop frame is installed on the card block, the bolt on the card block can avoid touching the stop frame and causing problems with uneven installation.

[0011] Preferably, the adjusting mechanism includes an adjusting body, a first stud and a second stud. A through slot is formed on the base block, and circular holes are formed at one end of the two base blocks facing each other. The first stud is fixed at one end of the slot away from the circular hole, the second stud penetrates through the circular holes of the two base blocks at the same time, and the adjusting body is located in the slot and is threadedly connected to the first stud and the second stud at both ends respectively. When the adjusting body rotates, it will tighten the first stud and the second stud on the same slot, so as to make the two base blocks approach each other, adjust the positions of the two card blocks, and adapt to the installation of stop frames of different sizes.

[0012] Preferably, the threads of the first stud and the second stud are opposite. When the threads of the first stud and the second stud are opposite, the adjusting body can rotate to make the first stud and the second stud approach or move away from each other.

[0013] Compared with the prior art, the adjustable stop frame profiling block proposed by the present utility model adopts the above technical solutions and achieves the following technical effects:

[0014] The present utility model can adjust the distance between the two card blocks by adjusting the distance between the two base blocks, and is applicable to the installation of stop frames of different sizes. The distance between the two base blocks can be adjusted infinitely by the adjusting body, and is applicable to the installation of stop frames of different sizes within the applicable range;

[0015] The present utility model can use different card blocks by disassembling and replacing the card blocks, so as to cope with the installation of different stop frames. Brief Description of the Drawings

At both ends of the substrate 100 formed by the base blocks 1 on the same surface, limiting blocks 3 are fixed by bolts. When the distance between the two base blocks 1 is adjusted through the adjusting mechanism 2, the interval between the two ends of the two base blocks 1 that are away from each other will increase or decrease, and their positions will change. On the surface of the limiting block 3 away from the substrate 100, clamping blocks 4 are fixedly installed by screws, and the two clamping blocks 4 will change with the position adjustment between the two base blocks 1.

[0023] For a specific embodiment, refer to Figure 1 and Figure 2 . The limiting block 3 is a cuboid, and the limiting block 3 is vertically installed on the substrate 100, that is, a right-angle bend is formed between the limiting block 3 and the substrate 100. The two limiting blocks 3 are installed on the same side of the substrate 100. Therefore, the two limiting blocks 3 are installed on the substrate 100 in the same orientation, and they are installed at two positions corresponding to the stop frame for limiting.

[0024] For a specific embodiment, refer to Figure 1 and Figure 2 . Two plate bodies 5 can also be installed on the upper and lower surfaces of the base block 1 through bolts. The two plate bodies 5 and the limiting block 3 are installed on the base block 1 in a U-shaped arrangement.

Among them, the ear tabs at the electrodes of the battery cell will be located in the mouth-shaped groove, and the two plate bodies 5 can protect the ear tabs to prevent the ear tabs of the battery from being damaged.

[0025] For a specific embodiment, refer to Figure 1 and Figure 2 . A card slot 31 is opened on the surface of the limiting block 3 away from the base block 1. The card block 4 is embedded in the card slot 31 and fixed by bolts. In this application, the limiting block 3 is a cuboid, the card slot 31 is a cuboid card slot 31, and the card block 4 is also a cuboid. During installation, the card block 4 can be installed corresponding to the card slot 31. The card block 4 can be restricted from rotating relative to the limiting block 3 within the card slot 31. The card block 4 is fixed by only one bolt, which can save materials and is convenient for replacing the card block 4.

[0026] In a further embodiment, the card block 4 can also have the same length as the depth of the card slot 31. A shape corresponding to the installation of the stop frame is provided on the card block 4, and this shape can play a role in limiting the stop block. At the same time, the card block 4 can be limited corresponding to the card slot 31.

[0027] For a specific embodiment, refer to Figure 1 and Figure 2 . A screw groove 41 for installing bolts is opened on the surface of the card block 4 away from the limiting block 3. The depth of the screw groove 41 needs to be greater than the thickness of the nut, and the diameter needs to be greater than the diameter of the nut. During installation, the nut can be completely located within the screw groove 41 for hiding, avoiding the problem that the protruding nut causes inconvenience in installing the stop block.

[0028] For a specific embodiment, refer to Figure 1 and Figure 2The adjusting mechanism 2 includes an adjusting body 21, a first stud 22 and a second stud 23. A slot 11 is provided on the base block 1. A circular hole 12 is provided at the opposite end of the two base blocks 1. The first stud 22 is fixed at the end of the slot 11 away from the circular hole 12. The second stud 23 passes through the circular holes 12 of the two base blocks 1 at the same time. The adjusting body 21 is located in the slot 11 and its two ends are respectively threadedly connected with the first stud 22 and the second stud 23. In this solution, there is a stagnation space in the middle of the adjusting body 21. When the adjusting body 21 rotates, the first stud 22 and the second stud 23 will continuously move into the stagnation space. At this time, the first stud 22 and the second stud 23 outside the adjusting body 21 become shorter, and the two base blocks 1 will be close to each other and fit together. The adjusting body 21 can be reversed to increase the distance between the two base blocks 1.

[0029] For specific embodiments, refer to Figure 1 , Figure 2 The threads of the first stud 22 and the second stud 23 are opposite. When only the threads of the first stud 22 and the second stud 23 are opposite, the distance between the first stud 22 and the second stud 23 will be reduced or increased after the adjusting body 21 rotates.
